I use a Canon Xsi and because Aperture 2 won't accept my raw photos (this seems to be a near-universal problem) I needed to use DNG, but then even DNG won't read accept them. I get the message "The source folder does not contain any supported camera raw files." I'm using DNG 5.3 and all of the files in the folder are .cr2. Any ideas?
DNG Converter 5.4.
I'm not very familiar with the Canon models, but it appears that your camera was supported prior to version 5.4. Are you trying to convert raw images or are they sRaw? Try converting regular raw images and see if that solves the problem. Otherwise, hopefully someone else will have a better idea.
